Waterproofing a facade doesn’t look like a DIY-job at first sight. Yet it’s a fairly simple job, once you know what and how to do it.

Oppercon is the perfect surface protection – it forms a waterproof, invisible shield against moisture, algae, mold and moss.

Make your stone wall water repellent with Oppercon.

Let us guide you through the steps…

Equipment and materials you need

Low pressure sprayer or paint-roller for larger areas

Brush for smaller areas

Covering the parts that need no Oppercon treatment
The Oppercon shield is not visible on the stone, but on glass, doors and window frames, it will become visible because it canít react with the stone. Therefore we recommend you cover up all the glass and parts that need no treatment with Oppercon
NOTE: Use a concentrated dishwasher soap, straight from the bottle and rub it on the glass, doors and the window frames. Oppercon will not stick on the soap. When you are done, simply remove the soap and youíll have clean windows as well.

Use a ladder for higher areas

Protective clothing and gloves
There is no need for special clothing. But we do recommend you wear rubber gloves, due to the alkaline (degreasing) character of Oppercon.

Step-by-step guide for waterproofing your facade / walls

Put on the rubber gloves and set up the ladder.

  • Fill the low pressure sprayer or bucket with Oppercon. Use a funnel so that you won’t spill any of it.Waterproof stones and walls with Oppercon.
  • Look at your project and think up a system so you know which area has been done and which need yet to be done. Start on a corner and work your way around.
  • NOTE: never go to lunch when youíre not done, finish the job in one take, then enjoy the result afterwords with a nice sandwich.
  • Spray from bottom to top.
  • In case the stone is old and porous, you can spray a second time, but do this before the first spay has dried.

NOTE: Never re-apply Oppercon on areas, where Oppercon has already dried up. If Oppercon has dried up it will no longer absorb anything, including itself. When this should occur, a white layer will appear.(remove this with a high pressure water cleaner).


Oppercon makes all stone and concrete water repellent and waterproof. It is UV-resistant and does not discolor the surface. Oppercon prevents the growth of algae, mould and moss on the surface.
